WALTON HARRISON, OF BLOOMFIELD, NEW JERSEY.

SIPHZON.

. Specification of Letters Patent.

Patented may 25, 1909.

Application filed November-28,1908. Serial No. 2642,5502.

T 0 all whom it may concern:

Be it known that I, WALTON HARRISON, a citizen of the United States, and a resident of Bloomfield, in the county of Essex and State of New Jersey, have invented a new. and Improved Siphon, of which the following is a fu, clear, and exact description;

My invention relates to. siphons and parts associated therewith, my more articular ob ect being to produce a siphon or-household use and'prov'ided with improved means for starting itinto action.

More specifically. stated,- my invention -comprehends a siphon vtube'to be inserted. 111430 a milk bottle or'other receptacle, and a dome of resilient material mounted upon the tion of a gent e lpressure b'y han air-tightj-f'upon t e' receptacle, next to transtube andada ted, .upon the sin'ple applicafirst to fit 'mit' air ressure momentarily to a liquid containe in the receptacle, and finally to collapse and permit the free ingress of air to As my invention may have many distinct forms, all embodying the same general principle,I' illustrate and describe only one rep resentative' form.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding arts in all the figures.

Figure l is a side e evation showing the. domeof resilient material mounted upon a siphon tube and applied therewith to an ordinary milk bottle containing milk to be siphoned; this view also showing a beaker for receivin the milk as removed; Fig. 2 shows the re ative position of the parts after the siphon is started into action; and Fig. 3 is'a detail of the im roved dome, considered by itself as an artic e of manufacture.

' The receptacle 4 is an ordinary milk bottle, filled with milk 5, just as delivered from a milk wagon. A siphon tube, preferablyv of glass, is shown at 6 and a beaker at 7. This beaker is provided with graduations 8 for automatically indicating the number of ounces of milk drawn off by tlie siphon tube.

At 9 is a dome of resilient material, preferably soft rubber, and provided with ribs 10 of the same material, integral with it. The dome is further. provided with a neck 11 which is merelyfan annular bearing surface. The neckis stretched a little, and-slipped over the tube, soas to fit thesame air-tight.

The dome is prnvided with'alarger annular bearing surface 12, slightly concave, and adapted to fit air-tight upon the milk bottle. The dome has ap roximately a hemispherical form, being s ightly flattened, however, at its top. By virtue of its general shape and the nature of the'ma.terial of which it is composed, the dome is adapted to turn inside out when a suitable pressure is a' .plied upon its top,andalso to automatical y retain, for the time bein the new shape Which'it thus assumes. The dome is so located upon the siphon tube that when the I parts are in normal position, as indicatedin lg. 1, the tube is supported entirely by the dome, the lower end of the tube clcariiiig the bottom of the bottleby a distance adequate to permit the dome to be compressed.

The operation of my devioe is as follows:

The dparts being in normal position, as indi-' cafe in Fig. l, the operator ays a hand upon the dome and suddenly applies a gentle sure to the same- There is, of course, a ittle volume of air within aud under the same,

and, as the dome is compressed, this volume tinned for a traction of a second longer, so

as todistort the dome considerably, it sudit retains automatically until-disturbed afterward. In doing this the ribs 10 are ex panded or stretched radially outward. If,

as may sometimes happen, the dome is not fitted properly or is operated clumsily and therefore tails to spring into the ideal shape indicated in Fig. 2, or, for any reason, fails to properly clearthe top of the milk bottle, the ribs 10, or some of them, engage the inner surface of the bottle neck and. bear the dome slightly away from the bottle so as to ermit free ingress of air thereinto. It will t us be seen that, While the dome 9 isin fact merely a single piece of rubber, and is operated by a single momentary application of ressure upon its top, it performs, in a do its order of succession, several distinct functions. That is to say, it first hugs tightly upon the bottle for a moment so as to form an air-tight joint, next applies an air pressure to the liquid, then gets out of the way so as to open the top of the bottle,

and finally expands its ribs as a precaution further insuring an adequate ingress ofair.

Iii-order to olean'the siphon tube and the its normal position.

donie, .the latter is slipped oil,- both are scalded or otherwise cleaned, and the dome is replaced upon thetube and sprung into Having thus described my inventiom' I claim. as newand desire to secure by Letters Patent; v

"1; The combination'of a siphon tube, and

a men ber of resilient, material connected therewith and adapted. to fit air-tight upon a. receptacle, said member being free to undergo distortion-for thepurpose ofdestroying its air-tight fit.

.2. As an article of manufacture, edema of resilient material provided centrally with an annular bearing surface and provided peripherally ith another annular bearing surface, said ome being further provided with ribs integral with-it and disposed ad- 'acent to said last-mentioned bearing sur ace. a a A 3.
